Speckle Reduction by Summation of Higher Order Harmonic Images
Granular patterns called speckles appearing in ultrasonic echo images have become a contributing factor to deteriorated picture quality. Speckle is a kind of statistical noise that does not depend on histological distribution but it’s average size is dependent on duration and beam width of ultrasonic pulses.
